Lotus Notes mail Access using c#

[C# Programming]

Hi All,

I m accessing the notes mail using notesDocument, I am able to get all teh properties of mail but if I want to access the mail like it is manually done, (color changes). how would I access the mail in that way..
My main problem is , I have infected file attach to lotusnotes mail and it is not detecting while I am accessing mail properties programmatically but if manually clicking it does..
I am using Domino dll for this automation.

Thanks
